Single-channel DACs

30 March 2011 Analogue, Mixed Signal, LSI

The MAX5214 and MAX5216 from Maxim are pin-compatible, 14-bit and 16-bit DACs. They are single-channel, buffered voltage-output devices which use a precision external reference applied through the high-resistance input for rail-to-rail operation and low system power consumption. The devices accept a wide 2,7 V to 5,25 V supply voltage range and feature a 3-wire SPI-/QSPI-/MICROWIRE-/DSP-compatible serial interface. Digital noise feed-through from input to output is minimised with SCLK and DIN input buffers which are powered down after completion of each serial input frame. On power-up, the ICs reset the DAC output to zero, providing additional safety for applications that drive valves or other transducers that need to be off on power-up.
